Motorcycle by David Kay Engineering

A private British  super vehicle collector has the bike for the past 17 years, during which he has displayed it as a work of art in the drawing room of his opulence home. Finally, he has now taken the decision to put his Ferrari 900 under the hammer.

David Kay wrote to Enzo Ferrari’s son Piero, requesting to have permission to build a one-off motorbike sporting the famous Ferrari prancing horse logos, and in May 1990 Kay got the reply he wanted: the approval to place the Ferrari logo on your motorbike. It was finished in 1995.

The bike, a Ferrari 900, which took Kay approximately 75 weeks to complete, has a 900cc engine producing 105hp, and is capable of 0-60mph in less than 3 second with a top speed of 257kmph. It was built from scratch and features a scratch built 900cc, transverse, double overhead camshaft, 4 cylinder, 8 valve unit with magnesium and alloy casings, driven through a 5-speed gearbox.

The two double curvature megaphone exhausts are too beautiful to merely funnel exhaust gasses from engine to atmosphere. The noise of this bike is like a Messerschmitt chasing a Spitfire,said David Kay.

Bonhams auction takes place in Stafford on April 29. A spokesperson from Bonhams said: This bike is in immaculate condition. This work of art is one of many headline bikes we have on sale this year. I have never in all the time I’ve been working here seen such an unbelievable standard of bikes, we’ve never had this standard of auction before.

cost of the bike would be US$139,066 (sold for £85,500) April, 2012 Stafford, U.K.
